Unfiltered inputs and outputs waste energy and interfere with nearby or attached electronics such as HAM Radio. Genasun worked to eliminated RF emissions from our line of charge controllers. Always on target Not all Maximum Power Point Tracking controllers were created equally. Most use a sweep and sleep method that scans the entire voltage range every 30-60 seconds. Traditional controllers are constantly off target during changing cloud conditions – exactly when power is scarce and is needed the most. Genasun controllers adapt to changing light conditions 15 times every second. They are always on target, capturing every bit of available sunshine. RFI silence Most MPPT solar charge controllers broadcast Radio Frequency noise from the DC/DC conversion circuit. Unfiltered inputs and outputs waste energy and interfere with nearby or attached electronics as HAM Radio. Genasun worked to eliminated RF emissions from our line of charge controllers. Smaller and lighter is a plus A unique high-frequency, patented technology designed to delivery each Watt to the battery without wasting energy into heat. No fans, no aluminum bars, no energy wasted. It means more efficiency, small dimensions, and lightweight. No drained battery The Genasun controllers won't drain your battery in stand-by mode or in the night. Only ~0.01 W for self-consumption makes the GVs unique MPPT solar charge controller. Check out the entire line of Genasun MPPT solar charge controllers. The unique low-power line of MPPT Buck and Boost solar charge controllers designed with a high-frequency, patented technology that allows the Genasun GV controllers to be the smallest, lightest, most efficient, and most RFI-quiet controllers on the market! Review: Works and happy with purchase - The Genasun GV-5-Li works perfectly with my 4S LiFePO4 battery. It’s compact, super efficient, and the MPPT charging really maximizes my solar panel output. I love the built-in low voltage disconnect. it protects my battery and connected load automatically. Simple to install and set up, and very reliable so far. Worth the price! Review: Good controller - I bought this for charging my lithium ion battery I use for my cpap machine when camping I had to set up my own connections and mount in a small box it works very well is heavy duty and is the only small portable ion solar controller I have found.unit seems to charge my ion battery faster than same solar panel and regular agm controller charge my agm battery the solar panel I use is the instapark 27 also very good product from desertcart...it is now 2019 and unit still in great working order. I have set it up, packed it up and moved it many times it gets bumped and jossled and still works ...good unit .. ## Features - Max. recommended panel power 65 W, 5 A charging current , charge profile CC/CV at 14.2 V for 4S LiFePO4 (3.55 V per cell) - High-Speed MPPT, speed tracking 15 Hz (15 times per sec.) - 99.85% Peak Efficiency and tiny night consumption (0.125 mA) - DC Load Output 5 A max with LVD (low voltage disconnect), ceramic capacitors, advanced electronic protections for reverse panel and battery - 10-Year Warranty, Made in the USA, conform to CE, FCC, RoHS ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #218,294 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #191 in Renewable Energy Controllers | | Customer Reviews | 4.5 out of 5 stars 41 Reviews | ## Product Details - **Brand:** Genasun - **Voltage:** 12 Volts - **Product Dimensions:** 4.3"L x 2.2"W x 0.9"H - **Material:** Ceramic - **Item Weight:** 2.88 ounces ## Images ![GV-5-Li-14.2V, 5 A MPPT Solar Charge Controller for Lithium (4S LiFePo4) Battery and 5 A Load Output with Low Voltage Disconnect (LVD) - Image 1](https://m.media-amazon.com/images/I/51pVgsjQk-L.jpg) ![GV-5-Li-14.2V, 5 A MPPT Solar Charge Controller for Lithium (4S LiFePo4) Battery and 5 A Load Output with Low Voltage Disconnect (LVD) - Image 2](https://m.media-amazon.com/images/I/41nsEWKSg2L.jpg) ![GV-5-Li-14.2V, 5 A MPPT Solar Charge Controller for Lithium (4S LiFePo4) Battery and 5 A Load Output with Low Voltage Disconnect (LVD) - Image 3](https://m.media-amazon.com/images/I/41m-XI0TBYL.jpg) ![GV-5-Li-14.2V, 5 A MPPT Solar Charge Controller for Lithium (4S LiFePo4) Battery and 5 A Load Output with Low Voltage Disconnect (LVD) - Image 4](https://m.media-amazon.com/images/I/51MDZhkHZ-L.jpg) ![GV-5-Li-14.2V, 5 A MPPT Solar Charge Controller for Lithium (4S LiFePo4) Battery and 5 A Load Output with Low Voltage Disconnect (LVD) - Image 5](https://m.media-amazon.com/images/I/61wMwpRLUSL.jpg) ## Questions & Answers **Q: is gv5 compatible with kilovault hlx battery?** A: Yes, the GV-5-Li-14.2V is compatible with 4S LiFePO4 like Kilovault battery. However, some manufacturers recommend a multi-stage charge profile, we suggest asking more info to Kilovault. **Q: Will it damage the controller if you disconect the battery with out disconnection the solar like other Life04 chargers?** A: The user manual says the recommended order of connection is panel, battery, load. It doesn't call out the disconnect order. I recommend contacting genasun or an authorized dealer for specific guidance. **Q: Do I have to use this chargers load out connection or can i hook my load directly to the battery?** A: Load to battery **Q: Does it stop charging below 0c 32f to protect the battery?** A: The Genasun controllers are programmed to charge with the max efficiency and under any conditions. The battery BMS must protect and disable the charge if the temp is below 0 °C (32 °F) and not the charge controller. That said, the GV-5-Li-14.2V is not programmed for that purpose, we suggest contacting the manufacturer as they also offer a CV version (custom voltage) that can disable the charge for low temp. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works and happy with purchase *by K***Z on July 16, 2025* The Genasun GV-5-Li works perfectly with my 4S LiFePO4 battery.
